ABSTRACT:
A disc gang for use with an agricultural implement includes a pair of front and a pair of rear disc openers mounted to a carrier boom by a mounting arm that can be independently raised and lowered as desired. The front and rear disc openers are mounted such that the openers can oscillate in response to surface undulations independently of one another. Moreover, the disc openers of each pair are free to oscillate in response to surface contours independently of one another.
